This project has evolved some , the basic rundown is I'm modding two Omnibots , one a regular the other a larger 2000 model. I will have two ezb kits , rad base idea was thrown out because of so much noise but could go back on the table if the omnibot drivetrain is too weak to pull it.

@robotmaker. , yes I fuse between , battery , power supply , before ezb ect , but I didn't draw them in.
No you can't run the cam from ezb digital out , you either must use a switching transister or Somthing to drop the voltage from your battery , connecting this cam to a digital port will smoke it. It draws between 200 ma to 500ma depending on charge level of the battery. See camera mod to bypass battery so this current draw is consistent and low as possible.
no not from digital output,from 5 volt output at the regulator ezb uses 5 volt low dropout regulator,and hight current i think its 5 or 7 amps i see other have the address up ,so can put mine up too i am in hallandale beach,fla ,also my email s [email protected] my main email [email protected] my girlfriend help make that name part jamaica part america part freddy my name,she a very pretty jamaican lady,been to jamaica 52 times so far
Linky to the solar charger/PSU unit pls?
Wow! this robot is definately taken on a life of its own! Congrats! Will you be using a pan/tilt joint within his shoulders? That would be a neat look!
@glick click , ugh everytime I hear a good idea my wallet gets a little lighter. (jk thanks
. I'm gonna measure when I get out of bed but that does sound like a good idea and could give the arms greater range of motion. I just recieved my pan tilt bracket for the neck.
@ndavid yea I recommend a solar charger because I could go from charging to running without interuption. It basically makes your bot have its own UPS backup. This is a 10th amp model good for most bots , but they come in 15a , 20a and higher... http://www.ebay.com/itm/150771239291?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I have two choices , either use a solar PSU or a ups backup brain and a regular PSU... I'm not afraid to go back and change Somthing that doesn't work efficiently but the key here is that it works
. Hope everyone has a good morning , I'm going back to bed its a little early for me to be up.
josh i see you are using a transistor and a relay for driving your vacuum,not a great idea ,much power lost,should use a mosfet,and will save you money too,mosfets can be driven from digital output using a 260 ohm resistor,mosfets are very common for this and h-bridges,and dc-dc convertersplus alot smaller in size
Can you please draw a diagram of how I would use a midget like that?
same as using a transistor ,only using a mosfet but will need a transistor to drive it i found a circuit on the internet close to it, use only Q1 and Q3 the mosfet ,plus R1 and R3 MOSFET CIRCUIT IT IS A H-BRIDGE circuit ,but you only using one mosfet mosfet part #IRF3205 IT IS RATED AT 110amps but anyone close to it will work without a heatsink needed D2 is not needed because this mosfet has one for protection
